Bought liquid damaged MacBook Pro from eBay worked fine when hard started. But power button didn’t work. Yesterday I finally replaced keyboard/backlight/ and power button. Keyboard and backlight work great but power button is still unresponsive and I still have to hard start the computer. Pretty sure it’s an SMC problem ( trackpad will click not scroll, fans running at high speed). Which I can’t reset without a power button to my knowledge. On earlier MacBooks there were spots on the logic board where you could reset the SMC. Unable to find one on this model . I have tried draining the battery disconnecting it and holding power button for 5 seconds then plugging into AC power to bypass SMC ( battery disconnected) with no luck. Also have reset pram erased entire hard disk and reinstalled lion. Is there a terminal command to reset SMC or a spot on the logic board? Or is this just unfixable and i just have to basically leave my computer on always.
As a work around try using System Preferences:Energy Saver->Schedule to turn on the computer. Fans running at high speed might be damaged sensors, a hot CPU Use the AHT (Apple Hardware Test) (command-D boot) for that machine may give you a clearer understanding of what problems exist.

It is possible through the rEFIt command prompt. Follow the instructions in the linked thread, but only perform this command: SmcFlasher.efi -reset 1 https://discussions.apple.com/message/22…
